The price will be dependent on the use. If this is a high horsepower project you may need high cost axles. If you can get away with a stock strength shaft you may be able to shorten a stock axle. I know in my area (northeast U.S.) both axle/driveshaft shops deal with large truck driveline repairs as their primary bussiness. Check with a shop that specializes in truck transmission, differentials etc. If they don’t make their own driveshafts ask them what shop they use.
